Lightningproof issues with chemical automatic control system were analysed. The lightningproof methods were explained emphatically.
本文分析了自动化系统的防雷问题,着重阐述了化工自动化控制系统的综合防雷措施。
In order to strengthen the stability and reliability of the system, lightningproof and static-free protection is improved and power trip protection circuits are added to to the design of senor power.
It is pointed out that in modern lightningproof and grounding systems, it is the structure of the equipotential system not the grounding resistance that matters.
